The time it takes to learn the piano differs from one person to another. Factors that tend to play a role in the difference include the time dedicated to studying and practicing the piano, the age of the learner, experience of the teacher, the learner's passion and their natural abilities.
The more time dedicated to studying the piano, the shorter time it takes to learn. Another factor to consider is that adults tend to learn faster than small children. Being taught by an experienced, knowledgeable and inspiring teacher also make learning easier. Additionally, learners who set aside regular practice sessions and those who are passionate about playing piano take a shorter time to master the craft. Some people have natural abilities that make the skill come easier to them, but practice is usually the greatest factor in learning.
